Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
As shown in fig. 1 and 2, an embodiment of the present invention discloses a mobile terminal including a housing 100, a driven device 200, and a driving mechanism.
The casing 100 is provided with a through hole 110, and the through hole 110 may be provided on a frame of the casing 100, through which the driven device 200 may pass, so that the driven device 200 enters and exits the casing 100. Specifically, the driven device 200 may include at least one of a camera module, a sensor, a fingerprint recognition module, a receiver, and a fill-in light, and may also include other devices that can enter and exit the housing 100. The driven device 200 is provided with a limiting portion 210, and the limiting portion 210 may be a protrusion, a groove, or other structures.
The driving mechanism is disposed in the housing 100, and can apply a force to the driven device 200 to move the driven device 200 relative to the housing 100, and specifically, the driving mechanism may include a magnetic member 310, a coil 320, and a first elastic member 330. The magnetic member 310 may be a magnet, and specifically, a neodymium iron boron permanent magnet may be used. The coil 320 is wound on the outside of the magnetic member 310, so that when the coil 320 is energized, it can generate a magnetic field, so that the magnetic member 310 is forced to move. The first elastic member 330 is connected to the driven device 200, and the first elastic member 330 may apply an ejection force to the driven device 200 to push the driven device 200 to eject out of the housing 100, which may be configured as a spring.
In an embodiment, when the coil 320 is in the energized state, if the direction of the magnetic field generated by the coil 320 is the same as the direction of the magnetic field of the magnetic member 310, the magnetic member 310 can move in a direction close to the position-limiting portion 210 and is in position-limiting engagement with the position-limiting portion 210, and at this time, the magnetic member 310 can limit the movement of the driven device 200, and even if the driven device 200 receives the force from the first elastic member 330, the driven device 200 will not pop out of the housing 100, and thus the driven device 200 is located in the housing 100 in this state. If the direction of the magnetic field generated by the coil 320 is opposite to the direction of the magnetic field of the magnetic member 310, the magnetic member 310 can move in a direction away from the position-limiting portion 210 and separate from the position-limiting portion 210, at this time, the magnetic member 310 no longer limits the movement of the driven device 200, and the first elastic member 330 pushes the driven device 200 to pop out of the housing 100, and then moves out of the housing 100.
As can be seen from the above description, the magnetic member 310 can be driven to approach the position-limiting portion 210 and be away from the position-limiting portion 210 by changing the power-on condition of the coil 320, so in an embodiment, the movement of the magnetic member 310 in the direction approaching to the position-limiting portion 210 and the direction away from the position-limiting portion 210 can be realized by the coil 320, but if such a structure is adopted, the coil 320 needs to be powered on all the time, the power consumption of the mobile terminal is increased, the service life is shortened, the maintenance cost is increased, and the user experience is deteriorated.
In order to solve the above problem, the coil 320 only realizes the movement of the magnetic member 310 in one direction, and the movement in the other direction can be realized by other structures. Optionally, the driving mechanism further comprises a second elastic member 340, wherein one end of the second elastic member 340 is connected to the housing 100, and the other end is connected to the magnetic member 310. If the coil 320 is powered on, the magnetic member 310 moves in a direction close to the position-limiting portion 210 and is in position-limiting engagement with the position-limiting portion 210, when the coil 320 is in the power-off state, the magnetic member 310 will be subjected to the force exerted by the second elastic member 340, so that the second elastic member 340 can drive the magnetic member 310 to move in a direction away from the position-limiting portion 210 and separate from the position-limiting portion 210. On the contrary, as shown in fig. 1, the solid arrows indicate the direction of the current flowing through the coil 320, the hollow arrows indicate the moving direction of the magnetic member 310, at this time, the direction of the magnetic field generated after the coil 320 is energized is the same as the magnetic field direction of the magnetic member 310, and the magnetic member 310 moves in the direction away from the position-limiting portion 210 and is separated from the position-limiting portion 210; when the coil 320 is in the power-off state, the magnetic element 310 will receive the force exerted by the second elastic element 340, so that the second elastic element 340 can drive the magnetic element 310 to move in the direction close to the position-limiting portion 210 and to be in position-limiting engagement with the position-limiting portion 210.
Further, the latter arrangement may be preferable because the mobile terminal is operated with a smaller frequency and a shorter duration of use of the driven device 200 by the user, that is, the driven device 200 is in the retracted state for a longer time. Therefore, after the latter arrangement is selected, when the driven device 200 is in the retracted state, the second elastic element 340 acts, and the coil 320 is in the power-off state, so that the power consumption of the mobile terminal is lower, and the service life of the mobile terminal is longer.
In the embodiment of the present invention, if a user wants to use the driven device 200, the power-on state of the coil 320 may be controlled, so that the magnetic member 310 is separated from the position-limiting portion 210, and the driven device 200 may be ejected out of the housing 100 under the action of the first elastic member 330. When the driven device 200 is used up, the user presses the driven device 200 to retract the driven device 200 into the housing 100, and at this time, the energization state of the coil 320 can also be controlled, so that the magnetic member 310 is in spacing fit with the spacing portion 210, and further the movement of the driven device 200 is limited, and the driven device 200 cannot be ejected out of the housing 100 even if the driven device 200 receives the ejection force applied by the first elastic member 330. Therefore, the driven device 200 does not need a motor and a transmission mechanism with a complex structure for telescopic movement, and therefore, the mobile terminal disclosed by the embodiment of the invention can solve the problems of high cost and complex structure existing when the motor is adopted to drive the telescopic device to stretch and retract at present. In addition, the driving mechanism has the advantages of simple structure, low cost, simplicity and convenience in assembly, safety, reliability, high flexibility, small occupied space and the like, and further meets the requirements of light weight, thinness and the like of the mobile terminal.
When the driving mechanism includes the second elastic member 340, it may be further provided that the extending direction of the second elastic member 340 is parallel to the moving direction of the magnetic member 310. That is, the deformation direction of the second elastic element 340 is consistent with the movement direction of the magnetic element 310, so that the acting force applied by the second elastic element 340 to the magnetic element 310 acts on the magnetic element 310 more effectively, thereby ensuring that the magnetic element 310 can be engaged with the position-limiting portion 210 more reliably or separated from the position-limiting portion 210 more quickly.
When the magnetic member 310 is driven by the coil 320, the magnetic member 310 moves relative to the coil 320. That is, the coil 320 may be fixed with respect to the housing 100, and the magnetic member 310 may move with respect to the housing 100. In order to prevent the magnetic member 310 from contacting the coil 320 and being worn when moving, a predetermined gap may be formed between the inner surface of the coil 320 and the outer surface of the magnetic member 310. The preset gap can be flexibly set according to actual conditions, and the preset gap is not limited in the text.
In order to simplify the structure of the driven device 200, the position-limiting portion 210 is preferably a position-limiting groove. When the end of the magnetic member 310 is located in the limiting groove, the two are in limiting fit, and when the end of the magnetic member 310 is moved out of the limiting groove, the magnetic member 310 no longer limits the movement of the driven device 200. Further, the limiting groove may penetrate through the driven device 200 along the thickness direction of the mobile terminal, so as to prevent the magnetic member 310 from being unable to reliably cooperate with the limiting groove when a small amount of displacement occurs in the thickness direction of the mobile terminal, and meanwhile, the limiting groove may be conveniently processed.
The structure of the matching part of the limiting groove and the magnetic member 310 can be flexibly selected, for example, the limiting groove can be a rectangular groove, and the end of the magnetic member 310 is a rectangular end head capable of being matched with the limiting groove. In another embodiment, the limiting groove has a first arc-shaped surface 211, and the magnetic member 310 has a second arc-shaped surface 311, and when the driven device 200 is located in the housing 100, the first arc-shaped surface 211 contacts the second arc-shaped surface 311. The first arc-shaped surface 211 and the second arc-shaped surface 311 can make the structure of the matching part of the limiting groove and the magnetic member 310 smoother, so that the two are not easy to scratch due to mutual contact, and the problem of stress concentration is not easy to occur, and therefore, the service lives of the two are prolonged.
In an alternative embodiment, the coil 320 may include a cylinder 321 and a coil body 322 wound around the cylinder 321, and the magnetic member 310 is disposed inside the cylinder 321. The barrel 321 may facilitate the positioning of the coil body 322 on the one hand and may provide guidance for the movement of the magnetic member 310 on the other hand. In order to prevent the abrasion between the cylinder 321 and the magnetic member 310, a predetermined gap may be formed between the inner surface of the cylinder 321 and the outer surface of the magnetic member 310, and the predetermined gap may be the same as the predetermined gap described above.
In order to prevent the cylinder 321 from shielding the magnetic field, the cylinder 321 may be provided as a non-metal member. The barrel 321 may be specifically a cylinder or other structure.
Since the first elastic member 330 is deformed during the process of extending the driven device 200 out of the housing 100 and retracting the driven device 200 into the housing 100, in order to provide guidance for the deformation of the first elastic member 330 and prevent the first elastic member 330 from bending laterally, the mobile terminal further includes a guide rod 400, the guide rod 400 is disposed in the housing 100, and the first elastic member 330 is sleeved on the guide rod 400. The guide rod 400 may limit the deformation direction of the first elastic member 330, such that the first elastic member 330 can be deformed substantially only along the moving direction of the driven device 200, thereby more reliably pushing the driven device 200 to eject out of the housing 100.
The mobile terminal disclosed by the embodiment of the invention can be a smart phone, a tablet computer, an electronic book reader or a wearable device. Of course, the mobile terminal may also be other devices, and the embodiment of the present invention is not limited thereto.
In the above embodiments of the present invention, the difference between the embodiments is mainly described, and different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory, and further description is omitted here in view of brevity of the text.
The above description is only an example of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
